I am about to car camp one week and I am wondering if I may safely carry some olive oil in a glass bottle - I expect day temperature to peak around 30 degrees Celsius.

I would like to know ahead of time if the oil is going to get rancid, or to deteriorate in any way.

Thank you very much

Olive oil will degrade over time, but that is measured in months and years if stored out of the light, and in cool conditions.

If you leave EVOO (extra virgin olive oil) in a glass container in sunlight, it will start to loose some of it's amazing flavour, astringency, and smell, but again this will take many days to be even slightly noticeable. It will still be safe to use.

Just don't leave a glass bottle of oil in the sunshine, keep it in a cool place (like under the seat in the car), and it will be OK.

If you have a few hours read up on it: http://static.oliveoiltimes.com/library/Olive-Oil-Storage-Conditions.pdf

The key point is that it takes 3 months at 37°C to ruin EVOO.

  • How cool? The OP's camping in 30C weather, so there's a good chance the two viable options are a car that's much hotter than 30C, or an ice chest.

  • @Jefromi Maybe we need a definition of car camping! Floor of car, under seat, will average much less than 30°C over a 24 hour period with daily peak at 30°C

  • Ah, you're assuming you can park in the shade, I think, or at least focusing more on the average than the worst 6 hours. Not sure it matters what the average is if it's in a 45C car for 1/4 of the time.

  • @Jefromi Floor of car should not rise above outside temp
